Try making your own animations and publish them on your group.
I had the same problem with “Realism”, where it was owned by my group but I needed animations. I uploaded the animation asset to the group and it worked perfectly fine.
I also believe you don’t need to upload animations. You can use them in your game instead. You can export the animation after inserting it and then edit it (possibly changing the priority to the correct one, if you haven’t already), and then reuploading it. This time, you upload it to your group. Change the ‘Owner’ dropdown box to your group.
